    We use the plugin to show query results from a mySQL DB inside a Confluence page. The Page consists of 2 different queries At the beginning we used Data Source Profiles Then we moved to application server datasources Since that transition, on Every login to the page one query succeeds while the other shows an exception (which one fails is random...) After doing refresh (once or twice) it suddenly returns result for both The exception is this [Partiial]: Error rendering macro 'sql' : Unexpected program error: com.mysql.jdbc.CommunicationsException: Communications link failure due to underlying exception: ** BEGIN NESTED EXCEPTION ** java.io.EOFException STACKTRACE: java.io.EOFException at com.mysql.jdbc.MysqlIO.readFully(MysqlIO.java:1913) at com.mysql.jdbc.MysqlIO.reuseAndReadPacket(MysqlIO.java:2304) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:2803) at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:1573) at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:1665) at com.mysql.jdbc.Connection.execSQL(Connection.java:3170) at com.mysql.jdbc.Connection.execSQL(Connection.java:3099) at com.mysql.jdbc.Statement.executeQuery(Statement.java:1169) at com.mysql.jdbc.Connection.getTransactionIsolation(Connection.java:3731) at org.apache.tomcat.dbcp.dbcp.DelegatingConnection.getTransactionIsolation(DelegatingConnection.java:353) at org.apache.tomcat.dbcp.dbcp.PoolingDataSource$PoolGuardConnectionWrapper.getTransactionIsolation(PoolingDataSource.java:250) at org.swift.confluence.sql.SqlMacro.process(SqlMacro.java:236) at org.swift.confluence.sql.SqlMacro.execute(SqlMacro.java:173) at org.randombits.support.confluence.ConfluenceMacro.execute(ConfluenceMacro.java:65) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.atlassian.confluence.macro.xhtml.XhtmlMacroManager$ResourceAwareMacroInvocationHandler.invoke(XhtmlMacroManager.java:225) at com.sun.proxy.$Proxy2518.execute(Unknown Source) at com.atlassian.confluence.content.render.xhtml.view.macro.ViewMacroMarshaller.marshalInternal(ViewMacroMarshaller.java:113) at com.atlassian.confluence.content.render.xhtml.view.macro.ViewMacroMarshaller.marshal(ViewMacroMarshaller.java:68) at com.atlassian.confluence.content.render.xhtml.view.macro.ViewMacroMarshaller.marshal(ViewMacroMarshaller.java:30) at com.atlassian.confluence.content.render.xhtml.UnmarshalMarshalFragmentTransformer.transform(UnmarshalMarshalFragmentTransformer.java:31) at com.atlassian.confluence.content.render.xhtml.transformers.DefaultFragmentTransformer.transformFragment(DefaultFragmentTransformer.java:153) at com.atlassian.confluence.content.render.xhtml.transformers.DefaultFragmentTransformer.transform(DefaultFragmentTransformer.java:129) at com.atlassian.confluence.content.render.xhtml.storage.StorageXhtmlTransformer.transform(StorageXhtmlTransformer.java:44) at com.atlassian.confluence.content.render.xhtml.TransformerChain.transform(TransformerChain.java:41) at com.atlassian.confluence.content.render.xhtml.PluggableTransformerChain.transform(PluggableTransformerChain.java:51) at com.atlassian.confluence.content.render.xhtml.DefaultRenderer.render(DefaultRenderer.java:80) at com.atlassian.confluence.content.render.xhtml.DeviceTypeAwareRenderer.render(DeviceTypeAwareRenderer.java:56) at com.atlassian.confluence.content.render.xhtml.DefaultXhtmlContent.convertStorageToView(DefaultXhtmlContent.java:155) at sun.reflect.GeneratedMethodAccessor1494.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.atlassian.plugin.osgi.hostcomponents.impl.DefaultComponentRegistrar$ContextClassLoaderSettingInvocationHandler.invoke(DefaultComponentRegistrar.java:129) at com.sun.proxy.$Proxy272.convertStorageToView(Unknown Source) at sun.reflect.GeneratedMethodAccessor1494.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.atlassian.plugin.osgi.bridge.external.HostComponentFactor .......
